The study sites of goldsbrough were the 1st site was by the freeway by Scott Hilburn auto The 2nd site was out Shelton mattock road about five miles to a bridge that went over middle goldsbourgh The 3rd site was little Egypt road Dates if studies The date of the study at the first site was Sept. 18, 1998 The date of the study at the second site was Sept.
21,1998 The date of the study at the third site was Sept. 25,1998 METHODS Physical check list, flow Tax, EPT Richness,How we got the flow for the 3 site was by measured off 50 feet then we dropped a leaf in the water and measured the time it took for the leaf to get to the end of the 50 feet then we recorded it on a piece of paper and repeated the process two more times and then divided it by 3 MacroinvertebratesFirst we measured off 1 square meter and then kicked debris into it from the whole meter and dumped it out and found all the little Macroinvertebrates and we did that with all three transects RESULTS Riparian health The riparian health was in fairly good condition except for site one there was a bank that was covered in rock and was eroding away and on the other side the habitat was in good shape in the other sites there was good over hanging trees for shade and debris in the river for fish and other macroinvertebrates to hide in. Woody debris in the stream for the fish habitat The amount of debris in the river was just about the rightamount for fish to hide and have a place to rest and to shade them from the sun and to provide a place for bugs to grow Erosion problems There was only one site that had an erosion problem and that was site one with one side of the inbankment falling into the river but the other side was fine the other sites were in good condition Substrate of the streambed – gravels silt The substrate at site one was in good condition there was good places for salmon to spawn, hide and rest in when they were making their way up stream. Except for the bank was eroding on the left side if you were looking up stream. The substrate at the second site was ok except for there was a hard clay like substance that lined the bottom of the whole area we surveyed.
At the third site the substrate was in good condition there was nice looking cobble and pebbles and there was no erosion on either sides of the banks Macroinvertebrates Tables for all sites # Taxa at each site
